Mechanics

Mechanics is the branch of science concerned with classical forces and the effect forces exert on (solid or fluid) physical bodies.

Theoretical and applied fluid mechanics relate to a large variety of topics such as: flow processes in the subsea and offshore industry, blood flows in thin canals and tissue, strong wave impact on wind turbines in the offshore environment, and on ship and offshore platforms, prediction and warning of long tsunamis caused by landslides, submarine slides and seismic motion, extreme ocean waves and invisible underwater interal waves in the ocean, oil- and gas transport in long pipelines and others.

 

 

Nonlinear water waves with effects of surface tension and turbulence are studied by the international research community, also studied in this research group.

About the group

In the research group, we are working with mathematical theories, experimental measurements using laser methods in the Hydrodynamics Laboratory, numerical methods and computations of such waves, flows and their impact. We work with model equations from theoretical physics, like variants of the KdV- and Schrödinger equations, other partial differential equations, integral equations and Green functions. We work with finite element methods (FEniCS) and computational methods in fluid mechanics with simulations of single- and multiphase flows including the motion of free boundaries like surfaces and internal waves.  We work with turbulence modelling (Large Eddy Simulations) and through the 4DSpace project we are now even investigating turbulence in space.

 

Cooperation

 

Local collaboration with Norwegian Geotechnical Institute, Institute for Energy Research, The Norwegian Defense Research Establishment and Simula Research Laboratory.  Collaboration on joint master and PhD course on Offshore Wind Power with Danish Technical University in Lyngby. Collaboration with several universitites in Europe (primarily University of Dundee, UK, University of St. Andrews, UK, Universidad de Alcalá, Sp and Ecole Centrale Marseille, Fr) and USA (MIT, Cornell University, Brown, Penn State, UCSD).
